John Miller, security research manager at Trustwave, said that the hack wasn’t due to a flaw in any of those company’s servers. “It was the individual users’ computers that had the malware installed on their machine,” he told ABC News. He adds that the unnamed hackers were most likely motivated by profit. “These passwords were never publicly posted. We can’t say for sure, but [the hackers] were probably going to sell them.”
